Abstract

The research aimed to reveal the emergence percentage of Science Process Skill (SPS) indicator on summative test of 10th grade in Surakarta in the academic year 2015/ 2016 and to find the capable alternative assessment instruments for measuring science process skill. This research was a descriptive research through the analysis of science process skill indicators on the summative test in Surakarta academic year of 2015/2016 and physics teacher questionnaire concerned teachers’ instrument in physics learning process. Questionnaires were given to 67 Physics teachers in Surakarta and surrounding areas as samples using random sampling technique. The summative test was chosen from public and private senior secondary schools in Surakarta, representing high, medium and low-grade schools based on the average national examination score over the past 5 years. Selection of summative test sample using purposive sampling technique. The resuls show that the achievement percentage of Science Process Skill (SPS) indicators on the summative test of 10th grade in Surakarta in the academic year 2015/2016 was dominated by the skill of applying concept and skill of planning experiment has the lowest percentage. The two-tier multiple-choice assessment instrument is one of capable alternative instruments to measuring students’ science process skills. In conclusion, the low percentage of occurance of science process skill indicator in summative test requires alternative instrument to measure students’ science process skill.
